Fire Extent and Severity Mapping (FESM) 2018/19

Fire severity is a metric of the loss of biomass caused by fire. In collaboration with the NSW Rural Fire Service, DPE Remote Sensing & Regulatory Mapping team has developed a semi-automated approach to mapping fire extent and severity through a machine learning framework based on sentinel 2 satellite imagery. The statewide severity map has standardised classes to allow comparison of different fires across the landscape. The FESM severity classes include: unburnt, low severity (burnt understory, unburnt canopy), moderate severity (partial canopy scorch), high severity (complete canopy scorch, partial canopy consumption), extreme (full canopy consumption).\r\n\r\nThis dataset represents the 2018/19 fire year, including wildfires >100ha with fire start date between July 2018 and June 2019.\r\n

火灾烈度是衡量火灾造成生物质损失程度的指标。新南威尔士州乡村消防局（NSW Rural Fire Service）与DPE遥感与监管制图团队合作，基于哨兵2号（Sentinel 2）卫星影像构建机器学习框架，开发了一套火灾范围与烈度的半自动化制图方法。该全州烈度地图采用标准化分级体系，可用于对比不同区域内的各类火灾。FESM烈度分级包括：未燃烧、低烈度（林下植被被烧毁，树冠完好）、中烈度（树冠部分焦枯）、高烈度（树冠完全焦枯，部分树冠组织被焚毁）、极端烈度（树冠完全被焚毁）。

本数据集对应2018/2019火灾季，涵盖起火时间介于2018年7月至2019年6月之间、过火面积大于100公顷的野火事件。
